Yes AP mode is working with the code in wireless-testing, expect that
the architecture code (mips) does not provide the sprom stored in the
flash to bcma yet. I just set a random mac address for the device and
wireless worked. I have not tested it much, just connected with a client
and got the same speed with iperf as b43 running in client mode. As no
additional changes where needed for AP mode I think b43 should already
support the same functionality when using N-PHY devices as with G-PHY
devices.
